2205不銹鋼管在低溫下，電阻、線膨脹系數(shù)、熱導(dǎo)率、質(zhì)量熱熔和磁性都會(huì)發(fā)生很大變化。電阻，線膨脹系數(shù)在低溫時(shí)變小；熱導(dǎo)率、質(zhì)量熱容在低溫時(shí)急劇減少；楊氏模量（縱彈性模量）在溫度下降的時(shí)同時(shí)增大。因?yàn)閵W氏體系列2205不銹鋼管具有低溫（Subzreo溫度）的Ms點(diǎn)（馬氏體***開始溫度或馬氏體生成溫度），所以當(dāng)保持在Ms點(diǎn)以下時(shí)，即可生成馬氏體。低溫時(shí)馬氏體的生成，才使奧氏體系列不銹鋼的**鋼種SUS304（18Cr-8Ni)在常溫下是非磁性，而在低溫環(huán)境中變?yōu)橛写判?。關(guān)于在低溫狀態(tài)下，鐵素體2205不銹鋼管存在像碳素鋼那樣的低溫脆性，而奧氏體鋼則不存在。因此鐵素體或馬氏體不銹鋼產(chǎn)生低溫脆化而奧氏體系不銹鋼或鎳基合金不顯示低溫脆性。鐵素體2205不銹鋼管的SUS410（13Cr），SUS430（18Cr)等在低溫狀態(tài)下，顯示出沖擊值急劇下降。所以，在低溫狀態(tài)下使用時(shí)，有必要特別注意。作為改善鐵素體系列不銹鋼沖擊韌性的方法，可考慮進(jìn)行高純化工藝。借助于控制C，N等級(jí)水平，脆化溫度在-50℃到-100℃范圍內(nèi)進(jìn)行改善時(shí)，有可能將其用于與冷凍相關(guān)的工程。近年來，已將SUS430LX（18Cr-Ti，Nb-LC)和SUS436L（18Cr-Mo-Ti。
